They seemed to have hinted at it though, but they didn't reveal it which made me sad face, oh well there's always hope an OVA or special will have it :D didn't want to risk an IShitHara instaban from TV for having a dick girl in it I guess.

I agree.
Sure this episode was full of sexual-innuendos, but it was really good, and thought out.

It seems that Lotte is really starting to have feelings for Naoya...she felt so bad when he got sick at the beach (most likely heat-stroke) She wanted to make some food for him to make him feel better. It seems like she does have a really sweet and caring side, when it comes to her "toy" Naoya :)

This show is disappointingly tame. I don't like seeing the succubus mother. However, the loli art and voice acting makes up for it.
Asuha's adorable innocence cements her as my favorite character, with her anti-pantsu stance pushing her over the top. Although, the pigtails in this episode do not look as good on her. They looked much better on Taiga.
I would use her for an avatar if the art released of her was equal to the Lotte art. Unfortunately, it is not.
Lotte and Ingrid trail closely behind in cuteness, but they are not as inviting.
I anxiously await the ecchi doujins.
Index still has the most adorable voice I've heard in an anime.
